Mechanism for eficiently supplying paint to a roller or brush

ABSTRACT

The invention relates to a mechanism for efficiently supplying paint to a roller or brush, formed by a suction/discharge pump including a deep cavity ( 1 ). The pump includes two externally threaded cylindrically-hollow extensions ( 5  and  5 ′) which are located diagonally opposite one another in relation to the cavity ( 1 ) and serve as connectors for attaching accessories, such as, for example, a brush, roller handle or hose. The lower extension ( 5 ) includes a narrow channel ( 7 ) which is connected to the cavity ( 1 ) and the other end of which is connected to a wide channel ( 6 ) into which is inserted a first valve ( 8 ) having a duckbill-shaped nozzle, made from a deformation-resistant material. The upper section ( 5 ′) has a similar structure to the lower section ( 5 ), but differs in that, instead of having a wide channel ( 6 ), this section ends in a tip ( 15 ) of equal thickness to that of the wide end ( 9 ) of the male connector, so that a second valve ( 8 ′) having a duckbill-shaped nozzle can be mounted thereon.

TECHNICAL FIELD OF THE INVENTION

The present invention relates to the technical field of building, specifically to the finishing steps: it provides a system to deliver pain to a brush or a roller.

BACKGROUND OF THE INVENTION

One of the problems that have arisen in the activity of painting buildings is the fact that the paint is thick, viscous and of a sticky consistency similar to honey, and therefore when dried stick in pieces and block ducts. It has a volatile chemical which tends constantly to create clot, grease and lump. Even when being filtered properly, paint can clog pipes at any time, either while being applied, or especially, when left at rest.

U.S. Pat. No. 1,829,850 explains new and useful improvements in brushes and particularly with a brush which is provided continuously a liquid or a solution coming from an attached container. The main problem of these pressure systems is that the consistency of the paint is uneven, if there is a clot stuck, when you open the valve that regulates the paint output, only a small trickle is injected, but then when the clot or lump of paint is released a burst of paint in ejected, besides this, the pressure in the paint container is not constant, nor is the difference in height between the container and the brush, which constantly rises and falls. Consequently, the painter has no control over the paint injected and can cause excessive runoff, so these systems work satisfactorily for rollers, which can hold inside significant amount of excess paint, while releasing little by little, it also work with a sprayer that spreads the paint directly on the paint surface. But it does not function properly with a brush, as the excess amount of paint that can be absorbed is minimal. Any excess which exceeds the capillary capacity of the bristles will spill.

U.S. Pat. No. 2,932,043 describes a mechanism for applying paint with four functional components, one being a spring in the exit valve, where there is force and where pressure is not critical, but it strengthens the seal at the top which is why where air can leak and remove the spring on the entrance valve, where what matters is the strength and not the seal. Even though it's a single spring, it is susceptible to corrosion. It also explains how its “check” valve can be disassembled and cleaned, but not in their internal parts to be assured that they leave no leaks and stay firmly secured, meaning that the internal part valves is inaccessible to wash. In addition, the spring, being thin and made of steel, is very susceptible to corrosion or cannot be replaced. Another disadvantage is that the suction pump lacks strength, but the inventor does not use a spring in the entrance valve, which would add suction strength and even if he explains that his pump have a sufficient strength to return to its original position and suction a thick fluid, this cylindrical design is simply inadequate to exert a significant suction force.

The patent application PCT/MX2006/000076 describes a paint supplying system for a brush or a roller, which have the following disadvantages: A difficult cleaning as a lot of paint gets stuck in the tubes and valves of the spring, the assembly of the upper and lower parts is very time consuming due to their shape and the model is very rustic, additionally the way in which the paint is distributed to the bristles is very slow and it takes time to distribute it correctly on the bristles of brush.

In order to eliminate all the mentioned inconvenient, a new improved painting system was developed that include means to efficiently deliver the painting, while also makes a strong emphasis on the versatility of uses and on the possibility to wash it. This invention allows to paint with an easy and continuous flow of paint in the bristles of the brush or plush of the roller, which I describe below.

Regarding the mentioned figures, the mechanism to efficiently deliver the paint to a roller or brush, is made up of:

A suction/expulsion pump to deliver the paint to a roller or brush, which in turn comprises an open cavity 1, preferably circular, similar to the one described in the patent application PCT/MX2006/000076, but with the difference that this cavity 1 is more profound (FIGS. 3 and 5) to provide more paint. The cavity 1 is hermetically sealed with a circular lid formed by a circular elastic membrane 2 whose perimeter 3 is thickened and strengthened so as to form a sort of ring, which is pressed into a channel 4 located on the upper outer part and which surrounds the cavity 1. Optionally, the cover has a tongue 2′ on its side, used to pull and remove the cover from the channel 4 that surrounds the cavity 1; so that channel 4 has a small cavity 4′ which holds the tongue 2′.

The cavity 1 has two externally striated and threaded extensions 5 and 5′, diametrically opposed to each other, which serve as connectors for attaching accessories such as a brush, a roller handle or a tube, among others.

The lower extension 5 has a narrow channel 7 which is connected to the depression of cavity 1 and have its other end attached to a wide channel 6 where is introduced a first valve 8 with a duckbill-shaped nozzle, made of an elastic material and resistant to deformation. This first valve 8 is mounted on the wide end 9 of a male connector shaped in an arrow form, so that in the wide channel 6 stay fixed said first valve 8 and the wide end of the connector 9, the nozzle being oriented towards the narrow channel 7, to allow the introduction of paint into the cavity of the pump. The other extremity 11 of the male connector is thinner and ends in an arrowhead, which is inserted into the narrow channel 13 of a removable piece 12 until the upper limit 10 of the male connector reaches the internal step of the removable piece 12; so it is clear that said removable piece is an open cylinder, which interior denotes two sections, the already mentioned narrow channel 13 and an upper channel 14 which is wider and internally threaded, to receive the external thread of the lower extension 5 so both parts stay assembled.

The upper extension 5′ of the paint supplying system, if similar in construction to the lower extension 5, with the difference that instead of having a wide channel 6, this one is ending in a tip 15 of equal thickness than the extreme width of the male connector 9, so that can be mounted a second valve 8′ with a duckbill-shaped nozzle, once mounted the valve 8′ is inserted into the cavity 16 of an arrow shaped female connector, whose tip 18 is inserted in a second removable cylindrical piece 12, until its limit 17 makes contacts with the internal step of said removable piece.

In this case the second valve 8′ stays oriented towards the arrow-shaped tip 18, in such a way as to allow the output of paint to the painting device.

The pieces described must have a construction that allows an hermetically assembly between said pieces, see FIGS. 2 and 3; but if necessary you can add a ring gasket 19 for this purpose.

In this way we have a mechanism that provides paints efficiently to the painting devices, since its suction/expulsion chamber is sealed and deeper, which allows a greater supply of paint, compared with the mechanisms already known. The pump works by applying pressure on the elastic membrane 2, if the cavity 1 is filled with paint, it tends to leave through the channel 7 of the upper extension 5′, passing through the exit valve 8′, to the point 18 of the female connector; when stopping to apply pressure on the membrane 2, it reverts back to its normal state, so it makes the cavity being refilled by paint coming from a container or pot which enters through the male connector, passing through then entry valve 8 into the cavity 1. Therefore, the mechanism must be sealed tightly, so vacuum is created and having only paint circulates inside.

This mechanism can be adapted to painting devices who self-supply themselves with this liquid, more specifically, rollers or brushes. I will proceed to detail some examples of application of this mechanism.

In the case of a roller, it is necessary to implement a handle to hold the roller (FIGS. 6, 7 and 8), where said handle is formed of a cylindrical body 24, preferably, inside which pass through a conduit 77 to allow the passage of paint, its upper extremity ends in an externally threaded bushing 26 for threading it with an internally threaded cap 27, and its inferior extremity terminates in an arrow-shaped tip 25 to have it connect to a flexible tube 29 which in turn is connected to the paint supplying mechanism described above. The threaded cap 27 has a central perforation 23, where it inserted the open end of a tube 20 which hold the roller plush 21, to have the paint continue his way through said tube 20 until exiting through a series of small perforations 22 which are located at the opposite end of the tube 20, so this tip should be closed, to force the paint to go out through the holes 22 and then moisten the plush 21 of the roller.

To the handle can be adapted a circular brush, as illustrated in FIG. 9, where the brush must have an internally threaded lower cavity 28 to be screwed into the tip 26, and therefore must provide a conduit 79 to allow the paint to exit through the bristles 45.

At the junction of the threaded cap 27 and the upper threaded end 26 of the body 24 of the handle can be placed a third valve 78 with a duckbill-shaped nozzle where the nozzle stay oriented towards the roller, in order to prevent the return of the paint to the components mentioned above.

In the inferior part of the paint supplying mechanism is added another stretch of flexible tube 29 exactly at the arrow tip of the male connector 11, which in turn connects to a conventional paint container paint (FIG. 11), where is added a filter 30 to the end of the flexible tube 29 that goes into the container, by means of copy 31. The function of the filter b is to prevent the entry in the flexible tube 29 of clots, lumps or any impurities that can be found in the paint.

In order to maintain an efficient supply of paint, an embodiment acquired by the present paint system is that is added a liquid heater, especially in geographic regions of low temperatures, for this, the liquid heater device is located between the stretch of the flexible tube 29 coming from the paint supply mechanism and the end of the flexible tube 29 coming from the container (see FIG. 26).

The construction of the liquid heater device is shown in FIGS. 12, 13 and 14, it is constituted of: an outer cylindrical tube 32 open at both ends, with both ends 34 internally threaded to screw a copy 35 on each extremities, forming an internal cavity which houses an inner tube 33 passing through to form a conduit through which pass the paint. Between the inner tube 33 junction with copy 35 is sealed with a circular package 37, to prevent the paint from spilling and prevent outside air from entering. Said heater includes electrical elements to heat the paint such as a sensor 38, a resistance sensor 39, an electrical resistance 40, a temperature controller 41 and electric cables 36, which can be placed between the space between the inner cylindrical tube 33 and outer cylindrical tube 32, or in another way suitable to a person skilled in the art. The space formed between the outer tube 32 and inner tube 33 is filled by insulating material 42, to protect the electric components and to prevent the heating of the outer tube 32.

Now, in the case of a paint brush, the suction/expulsion chamber described above, is inserted into the body 51 of the brush (see FIGS. 15, 16, 17, 18 and 19), so the lower mechanism is exactly the same, except that the inferior extension 5 is longer in order to be a part of the handle of the brush, while the upper section 5′ forms the body 51 of the brush. The body 51 has in its internal part, on the cavity 1, a channel 46 with an internal step, where is located a valve 52 with a duckbill-shaped nozzle, but with a different body than the valves already mentioned, as this valve 52 have a circular ledge in the middle, which is the part that rests on top of said channel 46, thus allowing the passage of the paint to a detachable base 44, so that said body 51 has in its upper part a longitudinally passing channel 43, where is inserted the detachable base 44 which contains the bristles 45.

The body includes at one of its extremity a fastener 47 and on the other end an opening 53, which serve to hold firmly to the detachable base 44.

The detachable base 44 is solid and has a vertical channel 48 for the passage of the paint; where said channel 48 must be in the same position as the channel 46 of the body of the brush, but have to be projected out and down from the base, by way of a transversal tubular ledge, so that can be inserted in it the nozzle of the valve 52; the tubular ledge has an outer ring gasket 54 to prevent the paint from coming out of this junction.

The base provides an outgoing hook 49 on the end where it is to secure the safe 47 and at the other end a ledge without hook 55 to be inserted into the opening 53, thus the base is securely fastened to the body of brush.

The upper perimeter edge of the detachable base 44 projects into thin walls 50, forming a container 51, where a tube 56 is inserted into the duct 48, to have the paint exit; on the perimeter and immediately after the thin walls 50 are mounted the bristles 45 while leaving a central space, where is first attached an outer plastic bag 57 opened in its superior part, and of a lower height than the bristles; then is placed a closed inner bag 58 of a lower height than the outer bag 57, with perforations 59 in its upper end, where said inner bag 58 holds in its interior and at the same height than the tube 56, a small bag 60 which covers said tube 56; so the small bag is open at its bottom and right side; therefore when the paint come out of the tube 56, it disperses to the other end of the inner bag 58, where the paint goes out through the perforations 59, before being poured into the outer bag 57, and finally be distributed to the bristles 45, achieving this way an uniform and constant flow throughout the whole brush.

A variant of the brush system is shown in FIG. 27, where to the detachable base 44, instead of having inserted in it the tube 56, the bristles 45 and the bags 57, 58 and 60, is inserted a tube that holds a roller, such as described in FIG. 8.

To the present system and all its variants can be optionally added a mechanism that provides vibration (FIG. 28), which is made up of a circuit 61 with its respective electric motor 62, a switch 63 and its respective power source 64. The disposition of this mechanism shall be to the convenience of one skilled in the art, as some components may be placed either inside or outside the body and the handle of the paint supplying mechanism. The vibration mechanism is intended to provide vibration to the painting system of the present invention, to cause a liquefaction of the paint in order to make it flow easily through the system.

To heat the paint, the following embodiment can also be used: the container or pot containing the paint becomes a portable heater, for that said container must be of a material resistant to high temperatures, because it will be heated by a resistor 65 that surrounds it externally (FIG. 30), which is connected to a power cable 66; on the container is placed on a vibration sensor 67 which detect the presence of vibrations and then shut off the power for safety, a temperature sensor 68 that interrupt the electrical current when the container is heated from 30 to 60° C., so that the paint do not overheat, a three-position switch 69, an inflammable and thermally insulated sleeve 70, used to cover the container components and keep it warm longer; and a strap 71 for carrying it.

In the cap 72 of the container is implemented a fireproof valve 73 which allows the entrance and exit of gases to be regulated in a controlled manner and prevents the paint to ignite.

For the cleaning or washing of the present system, the threaded cap 74, where is inserted the flexible tube 29, is designed to connect to a water faucet 75 and if the water inlet 75 is not threaded, then a connector 76 can be adapted.
